ADSL in the UK.

BT had this grand vision for basically providing rich multi-media through the phone line, but in ~1998. Think a mix of on-demand cable and "teleconferencing" with TV based internet (ceefax/red button on steriods)

It would have been revolutionary and kick started the UK's jump into online rich media.

However it wouldnt have got past the regulators as both sky and NTL(now virgin) would have protested loudly.
